PLUMBING SYSTEM.

Application filed June 19, 1922.

To all' whom it may concern:

Beit known'that I, JOHN-L. FRUIN, a citizenv ot the United States, residing in Chicago, in the county of Cook and State oit-Illinois, have invented certain new and useful Improvements in Plumbing Systems, of Which'thetollowing is a specification.

This invention relates to plumbing systems ofA the type designed tor use in multiple story buildings, and wherein the soil and venti'stacks and vent and waste branches connected thereto areall located within a vertical wall of the building, extending from the lower ioor to the roof, and are designed andadapted to serve'a plurality of bathroom and kitchen ixtures.

Plumbing systems ot this general type are in very extensive use, and have heretofore involved a quite complicated organization and arrangement offpipes and fittings for the accommodation of theV various fixturesserved, thereby involving considerable expense of material and labor in their installation. One object of the present vinventionl is to provide a plumbing system oi this type possessing greater simplicity of structure ranobfewerparts than similar systems now in vogue.

A further specific obj ect of the invention is to providea lumbing system ot `the type reterred tofa apted to serve both bathroom and' kitchen` fixtures which shall do away with what are known in the art as` jumpovers; that is, curved or bent portionsl in either the main ventpipe or a waste pipe which are situated in the same vertical plane and cross each other, thus making it neces- Sary to bow or bend one of the pipes outwardly past the other, v

A plumbing system assembled and erected in accordance with my present invention is illustrated in the accompanying drawing, in which- Fig, l is a vertical section-through the roof and several floors of a multiple story building showing my improved plumbing system in elevation therein; and

Fig. 2 is an enlarged horizontal section,

Serial N o. 569,452.

looking downwardly, on the line 2-2 ot Referring to the drawing, l, 2 and 8 indicatev the first, secondy and third floors, respectively, andR the root of a three-story building, and 4: and-5 designate the opposite sides of a hollow vertical wall structure which may be assumed to extend the full height of the three stories, within which my improved plumbing system is located. This latter includes the usual main waste and vent stack 6 extendinoV through the root R, and in which is inclut ed at each ot the three floors a sanitary waste and vent lixture 7 herein shown as embodying the structure of the sanitary T forming the subject matter of Letters Patent No. 849,383 granted to me April 9, 1907; but the specific structure of the said fixture is not materiali to the present invention.

Spacedl at some distance from the` main waste and vent stack 6 is the revent stack comprising mainly the vertical pipe sections 8 which extend through the second and third fioors.

Lying between the main waste and vent stack and the revent stack at each of the several floors, and communicating with both of said stacks, is a combined waste and vent branch assembly through which the lavatory L and-bathtub B are discharged and vented at all three floors, the closet C is vented at the first and second floors, and the kitchen sink S is vented at all three floors. An important element ot this combined waste and vent branch assembly consists of an integral or one-piece fitting, the same including a pair of vertical limbs 9 and l0, and horizontal upper and lower limbs 11 and l2, respectively, communicating with the vertical limbs 9 and 10. At the top licor 3, one end of the upper horizontal limb 1l is connected directly into the main waste and vent stack 6 by a horizontal pipe section 13; while on the second and lirst iioors the same end of the upper horizontal limb ll is connected into the lvent branch ot' the soil pipe titting 7 by connected horizontal the auxiliary waste inlet 16 of the soil pipe fitting 7 while the left end 17 of the lower limb 12 receives the drain pipe 18 from the bathtub B.

Substantially mid-height of the vert-ical limb 9 is a short lateral branch 19 which receives the drain pipe 20 from the lavatory L. The discharge pipe 21 from the closet leads into the main waste branch 22 of the soil pipe fitting 7 as usual.

My improved plumbing systemremploys for the discharge of the kitchen fixtures an auxiliary waste and vent stack leading into a catch basin; such auxiliary waste and? vent stack for kitchen fixtures being required by municipal sanitary regulations in some municipalities. Y

This auxiliary waste and vent stack is, in accordance with my present invention, located in the `same vertical plane with the main Waste and vent stack 6 and the revent stack 8, and preferably on the opposite side of the latter from the main waste and vent stack. As herein shown this auxiliary Waste and vent stack comprises mainly the straight vertical pipe section 23 extending through the three fioors and connected justabove the latter by Y fittings 24 herein shown as like those disclosed in Letters Pat- 'ent to Fruin and Valker No. 675,090, grant ed May 28, 1901; but the specific structure of said fitting is not material to the present invention. At the top floor the fitting 24 may be replaced by a simple straight fitting 24 having a lateral discharge branch 25. The fittings 24 are formed with lateral discharge branches 25 which, together with the branch 25 connect with the drain pipes 26 leading from the sinks S.

To properly vent the traps of the sink discharge pipes, the upper limb 11 of the top floor `fitting is formed with an integral downwardlyeturned branch 27 connected into the upper end of the fitting 24l the T head 11b of the fitting on the intermediate floor is formed with a downwardly-turned branch 27a entering the vent branch of the fitting 24; and .the upper limb 11 of the lower floor fitting has an integral down- Wardly extending branch 27b also connecting with the vent branch of the lowermost fitting 24. By means of the branches 27, 27@L and 27b of the several combined Waste an-dl vent vfittings the upper, intermediate and lower auxiliary waste pipe fittings 24 and 24 are vented to and through the revent stack and its top end connections to the main waste and vent stack.

The manner in which the several fixtures are discharged and their seals or traps vented to avoid danger of siphonage will be readily apparent to plumbers and others skilled in the art from the foregoing description ofthe structure and organization. It will be observed, however, that the vertical reventstack, which lies in the same vertical plane with the main and auxiliary waste and vent stacks, .is so situated relatively to the drain and vent pipes leading into the said stacks that jumpovers are avoided and only straight sections of pipe and fittings are required for the make-up of said revent stack.

Heretofore in erect-ing systems of this general type it has been customary to build up the intra-wall portions of the waste and vent branches of the lavatory and bathtub, and in some cases of the kitchen sink also, from a plurality of connected pipes and fittings, as typically illustrated in my former Patent No. 740,412, dated October 6, 1903. In my present invention I greatly reduce the number of individual pipe sections and fittings required by combining thesc several pipe sections'and fittings of the old art in a single integral fitting which includes a part that merges into and forms a` portion of the revent stack and likewise branches that connect up with the discharge fittings of an auxiliary waste and vent stack. Bearing in mind that the greater the number of joints in a plumbing system, the greater is the danger of leakage, it is manifest that my present system by materially reducing the number of joints, to that extent possesses more sanitary character and a higher degree of safety.

I claim:

1. In a plumbing system of the character described, the combination of a main vertical soil stack, an auxiliary vertical soil stack, a straight vertical revent stack disposed between said main and auxiliary soil stacks and nearer to the latter than to the former, a combined waste and vent pipe assembly for fixtures lying between and connected into said main soil and revent stacks, and a vent connection between said auxiliary soil stack and said revent stack.

2. In a plumbing system of the character described, the combination of a. main vertical soil sta-ck, an auxiliary vertical soil stack, a straight vertical revent stack disposed between and in the vertical plane of said main and auxiliary soil stacks and closely adjacent to the latter, a combined waste and vent pipe assembly for fixtures lying between land in the plane of said, main III said main and auxiliary soil stacks, a e0mblned Waste and vent pipe assembly for fixtures lying between and in tlie Vertical pla-ne of said main soil and i'eveiit stacks, and a pipe formed as .11 integral extension of a member of said assembly Connected into said auxiliary soil stack and venting the latter to said revent stack.
